[0002] As we all know, electronic cigarettes are electronic products that imitate cigarettes. When used, electronic cigarettes produce smoke by heating the smoke oil and atomizing the smoke oil. The existing electronic cigarettes are structurally provided with oil-conducting cotton to absorb the smoke oil, and further heat the oil-conducting cotton that absorbs the smoke oil through a heating wire to produce smoke.

[0003] A Chinese patent provides an electronic cigarette heating wire oil guide installation structure, with the publication number CN207744707U, comprising a heating wire sleeve with a hollow channel, a sleeve oil inlet hole connecting the hollow channel with the external space is provided on the side wall of the heating wire sleeve, a heating wire is installed in the hollow channel of the heating wire sleeve, the surface of the heating wire is coated with a ceramic coating, a heating wire sleeve bottom cover is provided at the lower part of the heating wire sleeve, the heating wire sleeve bottom cover limits the heating wire in the hollow channel of the heating wire sleeve, an electrode tube is provided at the lower part of the heating wire sleeve bottom cover, an insulating member is provided between the electrode tube and the heating wire sleeve bottom cover, and an air inlet hole connected to the hollow channel of the heating wire sleeve is provided on the electrode tube.

[0004] The above device has good oil conduction effect and strong oil absorption capacity, but the air inlet hole opened on the electrode tube in the device does not have the dustproof function, so that large particles of dust and foreign matter can easily enter the interior of the electronic cigarette and cause damage to the atomizer, electronic components and heating structure. At the same time, these impurities can easily accumulate inside the electronic cigarette and pollute it, reducing the service life of the equipment. Therefore, it is necessary to provide an embedded heating structure. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1) The embedded heating structure can ensure air circulation in the heating structure through the air intake holes on the air intake pipe. The dustproof air tube arranged in the air intake pipe can filter the external gas entering from the air intake holes, so that impurities and dust in the external air can be filtered and blocked, preventing large particles of dust and foreign matter from entering the electronic cigarette and causing damage to the atomizer, electronic components and heating structure, thereby extending the service life of the device.

It has good dustproof effect and good sealing performance, effectively avoiding the problem of impurities accumulating inside the electronic cigarette and polluting it, thereby reducing the service life of the equipment.

[0023] See also Figure 2-Figure 4 , it is further obtained that a threaded ring 9 is fixedly provided at the bottom of the electrode tube 8, a threaded sleeve 11 is fixedly provided on the air inlet pipe 10, the threaded sleeve 11 is threadedly connected to the threaded ring 9, an air inlet hole 12 is opened on the air inlet pipe 10, a dustproof air cylinder 15 is arranged in the air inlet pipe 10, an extrusion ring 13 is extruded and contacted above the dustproof air cylinder 15, the extrusion ring 13 is sealingly and slidably connected to the inner wall of the air inlet pipe 10, a spring 14 is fixedly provided at the upper end of the extrusion ring 13, the upper end of the spring 14 is fixedly connected to the inner wall of the air inlet pipe 10, a bottom cover 16 is arranged below the air inlet pipe 10, an external thread groove is opened at the lower end of the air inlet pipe 10, an internal thread groove adapted to the external thread groove is opened on the bottom cover 16, and the air inlet pipe 10 and the bottom cover 16 are threadedly connected through the external thread groove and the internal thread groove.

[0024] Specifically, the air inlet hole 12 opened on the air inlet pipe 10 can ensure the air circulation in the heating structure, and the dust-proof air tube 15 arranged in the air inlet pipe 10 can filter the external air entering from the air inlet hole 12, so that the impurities and dust in the external air can be filtered and blocked, and large particles of dust and foreign matter are prevented from entering the electronic cigarette, causing damage to the atomizer, electronic components and heating structure, thereby extending the service life of the device; by rotating and disassembling the bottom cover 16, the dust-proof air tube 15 is ejected, and the dust-proof air tube 15 is easily removed. For cleaning or replacement, when installing the dust-proof and breathable tube 15, the bottom cover 16 is threadedly connected to the bottom of the air inlet pipe 10, and the upper end of the bottom cover 16 is tightly against the bottom of the dust-proof and breathable tube 15. The upper end of the dust-proof and breathable tube 15 squeezes the squeezing ring 13, and the squeezing ring 13 is always tightly against the upper end of the dust-proof and breathable tube 15 due to the rebound force of the spring 14, so that the dust-proof and breathable tube 15 is firmly fixed in the air inlet pipe 10, with good dust-proof effect and good sealing, which effectively avoids the problem of impurities accumulating inside the electronic cigarette and polluting it, thereby reducing the service life of the equipment.

[0025] In actual operation, the oil is injected into the oil storage tank 6, and the oil in the oil storage tank 6 flows into the space in contact with the heating wire 2 through the oil inlet hole 7 on the sleeve 1. The ceramic coating on the surface of the heating wire 2 absorbs the inflowing oil. When the heating wire 2 is powered on, the oil in the ceramic coating is atomized and generates smoke under the heating effect of the heating wire 2, and the smoke flows out through the upper end of the channel of the sleeve 1.

[0027] When it is necessary to clean or replace the dust-proof air cylinder 15, the bottom cover 16 threadedly connected to the bottom of the air inlet pipe 10 is first rotated and disassembled. At this time, the spring 14 is no longer squeezed and begins to release the resilience. The squeezing ring 13 pops out the dust-proof air cylinder 15 under the rebound of the spring 14, and the dust-proof air cylinder 15 can be removed for cleaning or replacement. Finally, the cleaned or replaced dust-proof air cylinder 15 is put into the air inlet pipe 10 again, and the bottom cover 16 is threadedly connected to the bottom of the air inlet pipe 10. The upper end of the bottom cover 16 is tightly against the bottom of the dust-proof air cylinder 15, and the upper end of the dust-proof air cylinder 15 squeezes the squeezing ring 13. The squeezing ring 13 is also subject to the resilience of the spring 14, so that the squeezing ring 13 can always be tightly against the upper end of the dust-proof air cylinder 15, so that the dust-proof air cylinder 15 can be firmly in the air inlet pipe 10, with good dust-proof effect and good sealing, which effectively avoids the accumulation of impurities in the electronic cigarette and pollution thereof, thereby reducing the service life of the equipment.
